It's a great episode, but I've never bought into the "ethical dilemma" aspect. What's the dilemma? If Sisko doesn't bring the Romulans into the war, then the Federation loses and the Dominion conquers the Alpha Quadrant.
Because to protect the ideals of The Federation he has to break the ideals of The Federation.
right, but if there is no Federation left because they lose the war, protecting their ideals would be a moot point. A dilemma only qualifies if there's a relative balance of potential outcomes. In the episode, the "dilemma" was "violate your personal ideals vs. watch the Federation lose the war and be conquered, possibly enslaved."
That's an easy choice, not a dilemma.
